The baking soda, water, and sugar react and create fizzing which is a result of a chemical reaction because it shows that a new gas has formed. 
Baking soda/water chemical equation: NaHCO3 + H2O → H2CO3 + (OH-) + (Na+).]]> 2021-04-19 18:39:06 UTC https://padlet.com/harrisonerdman2025/apqs9ixtbry9ik8u/wish/1434676174 harrisonerdman2025 https://padlet.com/harrisonerdman2025/apqs9ixtbry9ik8u/wish/1434733448 Alka Seltzer and water mix to create a chemical reaction. The water starts to bubble and fizz because of a new gas is created. Because a new gas is created it is a chemical reaction. 
Alka seltzer and water equation: 3NaHCO3 + C6H8O7 → C6H5Na3O7 + 3CO2 + 3H2O

An example of this is the Statue of Liberty. It was originally brownish until it eventually turned green. This is a chemical reaction because new pigments are in the new substance that is made when copper reacts with the elements.
